What will happen when a marshmallow dissolves in vinegar?

When a marshmallow is dropped in vinegar, the acetic acid in the vinegar reacts with the gelatin in the marshmallow to form a soft, gooey substance. This is because the vinegar causes the gelatin to denature, which means that the protein molecules break down and lose their structure. The marshmallow will also start to lose its shape and become more transparent as the gelatin dissolves.

In addition to the chemical reaction that takes place, the marshmallow will also undergo a physical change. As the gelatin dissolves, the marshmallow will start to absorb the vinegar, which will cause it to swell and become heavier. The marshmallow will also become more difficult to hold onto, as the surface will become slippery.

The marshmallow will eventually dissolve completely in the vinegar, but the process can take several hours or even days. The time it takes for the marshmallow to dissolve will depend on the concentration of the vinegar and the temperature of the solution.
